EMI-103 is a rack-mounted printed circuit board from the Terasaki EMI card series. Based on its front panel, it acts as the central card of an ICU (the abbreviation shown on the faceplate) inside a Terasaki control panel: it holds the stored program (EPROM LC-A 106), reports an abnormal ICU condition through the red LED, can be re-initialised with the INIT. switch, and offers a loader connector for programming or data transfer. The card plugs into a back-plane through a gold-plated edge connector and is fixed with two front-panel handles/screws.
The exact name of the Terasaki system in which EMI-103 is installed was not verified from manufacturer documentation. Terasaki cards of this family are widely used in shipboard switchboard, generator control and power management panels.

We ship worldwide by DHL, FedEx, UPS and other couriers, and can deliver to ships through agents in major ports.
Many vessels built in the 1990s and 2000s still operate Terasaki control panels with EMI-series cards. Replacing a complete panel is expensive and needs class approval, so ship owners prefer to replace a single faulty card. Reliable supply of tested cards such as EMI-103 keeps these systems running safely and at low cost.
